[NTG-context] Undefined control sequence.

[Bernd Militzer]

Hi,

for a large project I defined names for a lot of persons like

\global\def\PIDacht{Militzer, Hermann Paul (8)}
\global\def\PIDeinsacht{Militzer, Johann Wilhelm Hermann (16)}
\global\def\PIDdreidrei{Militzer, Henriette (33)}
\global\def\PIDachtviervieracht{Militzer, Adam (8448)}

\starttext
\PIDachtviervieracht
is ok

but

\section[UkPID8A]{\PIDacht\ -- Allgemein}
does not work!
\stoptext

I get:
(./FamMilitzerUrkunden.tuo) (./FamMilitzerUrkunden.tuo
! Undefined control sequence.

                    \ -- Allgemein

What is wrong?
